GUIDE SPECIFICATION FOR VOCOMP®-30: WATER-BASED ACRYLIC CURING AND SEALING COMPOUND

SECTION 0305 00

COMMON WORK RESULTS FOR CONCRETE

Specifier Notes: This guide specification is written according to the Construction Specifications Institute (CSI) format. The section must be carefully reviewed and edited by the architect or engineer to meet the requirements of the project. Coordinate this section with other specification sections and the drawings.
Specifier Notes: VOCOMP-30 is a readytouse, 30% solids concrete curing and sealing compound formulated of special acrylic polymers in a true water-based carrier. VOCOMP-30 provides improved resistance to rain, sun, freezing temperatures, most acids and industrial chemicals, petroleum, deicing salts, cleaning agents (except aromatic solvents), diluted caustics, and other pollutants. Color-wise, VOCOMP-30 appears milky white in the container and, when first applied, leaves a bluish cast on the concrete for easy visual coverage. VOCOMP-30 dries clear to provide a transparent sheen finish. This sheen can be controlled by the number of coats applied.
VOCOMP-30 may be used wherever a thicker film, with a medium-to-high sheen, is desired to bring out the natural beauty of concrete without discoloring, checking, or peeling. When properly applied, VOCOMP-30 provides a premium-grade seal for superior moisture protection. It may be applied to simultaneously cure, seal, and dustproof new, old, interior, exterior, horizontal, and vertical concrete surfaces. VOCOMP-30 is ideal for curing, sealing, and dustproofing driveways, sidewalks, patios, swimming pool areas, and commercial and industrial floors. Horizontal surfaces protected with VOCOMP-30 offer excellent wearing qualities for foot and vehicular traffic. If, after prolonged usage, traffic patterns appear, the surface can be washed clean and recoated to restore the original beauty. Good concrete and good concreting practices should be used, as VOCOMP-30 is not a cure-all for improperly mixed or placed concrete.
